The best spaces leave room for the things that matter. A window, a quiet corner, and a little natural light can change the way we work.

The shape of everyday things

Every familiar object carries a series of decisions about how it will be held, used, and understood.

Found in the text, not just the title.

Keep it

Pages disappear.
Your offline copy stays.

Save an offline copy before a page changes or goes away. Read it on a flight, highlight a passage, and find it again later.

A slower kind of weekend

Follow the coast until the road gets quiet. Leave an afternoon unplanned.

iCloud sync

Save anywhere.
Find it everywhere.

Save a bookmark on your desktop, laptop, iPhone, or iPad. Your own iCloud brings it to the others, so the same library is ready wherever you pick up.

How iCloud sync works

Saved on Desktop. Available everywhere.

Use the same Apple Account and turn on iCloud Drive on each device. Changes sync when you’re online.

It is yours

No account.
Your iCloud.

Your library lives on your devices and in your own iCloud. A daily library backup goes to iCloud Drive. Export in HTML, CSV, JSON, or Markdown, with files and offline copies.

A closer look at privacy

Save from any app

A good find.
Saved before you leave.

Use the Safari toolbar on Mac, or the share sheet on iPhone and iPad. Choose a collection, add tags and a note, then save a page, files, or text. In Safari on Mac, selected text can become a highlight.

Set up the Safari extension

Save from anywhere

One library.
All the things you keep.

Links. PDFs. Files. Notes.

Use the Share button in any app, the Safari extension on Mac, or drag and drop. Keep links and files together, then find them with Spotlight, Siri, and Shortcuts.

Answers to the everyday questions.

What happens at 50 items?

Your items stay. You can still read, search, and organize your library. To save more than 50 items, get Rainbow Index Pro. Items in Recently Deleted do not count toward the limit.

Is Pro a subscription?

No. Pro is a one-time purchase that removes the item limit on your iPhone, iPad, and Mac. Family Sharing is included.

Where is my library?

On your devices and in your own iCloud. There is no Rainbow Index account and no Rainbow Index server storing your library. Use the same Apple Account on each device to sync.

Does it work offline?

You can browse, search, and organize the items on your device without a connection. Download offline copies before you need them. Changes sync through iCloud when you are online again.

Can I take my library with me?

Yes. Export your library as HTML, CSV, JSON, or Markdown, with your files and offline copies. Rainbow Index also keeps a daily backup in your iCloud Drive. You can export without Pro.

Does the AI send my library anywhere?

No. Summaries, suggestions, and answers run on your device with Apple Intelligence. They require a supported device and Apple Intelligence availability in your language and region. The rest of your library works without them.
